Tiny changes in Earth’s rotation may reveal a tug-of-war between its deformable inner core, liquid outer core and deep mantle ...

The new map highlights six regions that had been poorly sampled by PKP precursor studies and now appear to be promising ...

Add Yahoo as a preferred source to see more of our stories on Google. While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is ...

A battle of forces, driven by the motion of Earth’s core, can explain small variations in the planet’s rotation, study finds.

Deep inside Earth, far below the crust and mantle we learn about in school, scientists are mapping strange, continent-sized structures that appear to shape everything from volcanic hotspots to the ...

An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior of earthquake waves, in Earth's inner core. A team led by scientists from ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

Far below your feet, nearly 1,800 miles beneath oceans and continents, Earth carries two massive scars from its violent youth. They are so large they rival continents in size, yet no human will ever ...

The illustration shows a cutaway revealing the interior of early Earth with a hot, melted layer above the boundary between the core and mantle. Scientists think some material from the core leaked into ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...
